Controlling Trolls

To begin with, there are people in the world that are social media addict. These people are most of the young people , including myself . But social media isn't for everyone ,there are people who abuse it, by abusing other people. They say harsh things on other's posts and they can be really hurtful . Most students consider "roasting" like a sport. you talk bad about someone to only get a worst response from them and you go back and forth until someone has ran out thought that can potentially embarrass someone. Question is can these trolls , the ones that go under someone else page not home around with them but hurt them be controlled ? My answer about it is no. Though ignoring someone may seem like the best way to fight the troll. Or you aren't sure if responded will keep them quited or  hype them up. The issue is that trolls are dangerous and depending circumstances they must be stopped .
